Abstract: The present invention relates to the diagnosis of the risk of experiencing a cardiovascular complication in the context of treatment with erythropoiesis stimulating agents (ESAs) such as erythropoetin and derivatives thereof, particularly in the context of anemia. More particularly, the invention provides a method for diagnosing the risk of a patient of experiencing a cardiovascular complication as a consequence of future medication with an erythropoiesis stimulating agent (ESA), comprising the steps of (a) measuring the level of a BNP -type peptide in a sample of the patient, (b) diagnosing said risk by comparing the measured level of the BNP -type peptide to at least one reference level. The BNP -type peptide may for example be brain natriuretic peptide (BNP) or the N-terminal fragment of BNP, NT-proBNP. The cardiovascular complication may include complications such as stroke, transient cerebral ischemic attack, acute coronary syndrome, myocardial infarction, congestive heart failure etc.. Notably, the present invention also relates to dosages of ESA medication which do not cause hyperviscosity.

Title: Oxidative internal breaker for viscoelastic surfactant fluids
Inventor: ABAD CARLOS
IPC: E21B43/25
Filed: 2007-09-12
Abstract: Compositions and methods are given for delayed breaking of viscoelastic surfactant gels inside formation pores, particularly for use in hydraulic fracturing. Breaking inside formation pores is accomplished without mechanical intervention or use of a second fluid. Oxidizing agents such as air, oxygen, persulfates, bromates, peroxides, and others are used. The break may be accelerated, for example with a free radical propagating species, or retarded, for example with an oxygen scavenger. In certain brines, for example bromide brines, certain zwitterionic viscoelastic fluid systems that can decarboxylate and that require an anion-containing co-surfactant undergo delayed degradation if oxygen is present, for example from fluid preparation or in a foam.

Title: Multiple punch and die assembly providing hand disassembly, punch length adjustment and replacement
Inventor: THIELGES BRUCE M
IPC: B26D5/08
Filed: 2007-06-07
Abstract: A multiple punch and multiple die assembly has a workpiece protector comprising a punch lifter that is operatively associated with each punch for supporting each of the punches in an inactive position as an active punch is moved by the ram to the active, i.e. operating position to thereby eliminate scoring or marking of the sheet material or other workpiece that is being punched. To eliminate the need for hand tools and hand assembly or disassembly, a manually moveable retainer on the punch assembly is provided that can be moved by hand between a punch-releasing and punch-retaining position for holding the punches within the multi-punch assembly during operation. To prevent stress fractures that formerly occurred in die carriers, support of each die is distributed between two different die components thereby reducing impact stress on the carrier as the ram drives the punch through the workpiece.
